Computer Controlled Ventilation Trainer

Scaled ventilation training unit enables students to study basic airflow and fluid mechanics as well as process of commissioning and balancing a multiducted air distribution system.

Metallic structure. Panels and main metallic elements in stainless steel.

Diagram in the front panel with similar distribution that the elements in the real unit.

Variable speed centrifugal fan, computer controlled:

Supply pressure up to 350Nm-2.

Flow rate: 1400 m3 h-1 approx.

Rectangular air intake and filter holder.

The fan discharges into a 200 mm diameter steel duct and this connects to distribution ductwork.

Connections and ductwork are manufactured in steel and may be connected in different forms.

The ductwork is supported from air distribution isolation mounts hung on steel pedestals linked together.

Necessary components are supplied with the unit to enable parallel branch and line balancing experiments to be undertaken.

Air power supply points are provide that may be balanced on the assembled unit to supply a range of airflows.

Pressure sensors.

Flow sensors.

Pilot static tube.

It can be controlled by computer by using control interface box and data acquisition borad to be placed in the computer solt.

 

Some Practical Possibilities of the Unit:

1.-   Examination of typical components, fabrication, installation and assembly techniques used in air handling systems.

2.-    Investigation of pressure losses in beds, branches, changes of section and over straight lengths of duct, together with the variation in pressure drop with velocity.

3.-   Measurement of air flow rate using pitot-static traverse, orifice pressure differential and anemometer methods.

4.-   Examination of standard types of panel an bag filters and their pressure drop against face velocity.

5.-   Determination of the “k” factor for the pressure loss of the above components in each particular configuration.

6.-   Investigation of the fan pressure and volume flow characteristics at various supply voltages.

7.-   Balancing of air flow distribution in a series or two branch parallel distribution system using either main damper or fan speed flow control.

8.-   Allows an additional parallel branch and two diffusers to be investigated.

9.-   Addition of the ductwork leakage test set allows students to carry out commissioning leak testing on the above components.

10.- Allows  an additional tee branch and two diffusers to be investigated.

11.- Sensors calibration.

Practices to be done by PLC Module (PLC-PI)+PLC Control Software:

12.- Control of the TEVC unit process through the control interface box without the computer.

13.- Visualization of all the sensors values used in the TEVC unit process.

14.- Calibration of all sensors included in the TEVC unit process.

15.- Hand on of all the actuators involved in the TEVC unit process.

16.- Realization of different experiments, in automatic way, without having in front the unit.(This experiment can be decided previously).

17.- Simulation of outside actions, in the cases do not exist hardware elements. differential and anemometer methods.(Example: test of complementary tanks, complementary industrial environment to the process to be studied, etc).
